assembly instructions
1. Remove the spreader and components from box and place
hopper up-side down on a padded surface as shown. Slide drive
and free wheel onto axle as shown with the longer portion of
wheel hub facing the frame. Secure free wheel with (1)
1/8” dia. x 1-1/4” cotter pin. Attach drive wheel to axle with (1)
3/16” dia. x 2” cotter pin.
3. Turn spreader upright on wheels. Insert screen into hopper
sliding it under the screen clips. Attach the upper handle as-
sembly to handle brace with the handle lever facing as shown.
Secure with (2) 1/4-20 x 1-1/2” carriage bolts, and lock-nuts.
4. Install control rod to handle lever with a 1/4” dia. clevis pin.
Thread (1) 5/16” hex nut onto the control rod until it is roughly
in the middle of the threaded area. Next, Install all three friction
washers on the spring housing rod. Place the L-Bracket on the
end of the spring housing rod and secure with the 3/32” cotter
pin. Slide the end of the control rod through the L-Bracket mak-
ing sure there no tension between the hex nut and the L-Brack-
et. Set the rate control plate to the “B Position”. Flip control lever
to the “On Position”. Check port gap. Adjust the threaded nut on
the threads until the port opening is “just” open when lever is
in the “On Position”. With the lever in the closed position install
the second 5/16 Hex Nut on the control rod. Tighten both nuts
against the L-Bracket.
2. Attach leg/brace to frame as shown using (4) 1/4-20 x 2-1/4”
carriage bolts and lock-nuts.

Normal spreading of materials requires no adjustment (Factory
setting “A”) unless stated on the package. In those cases where
the spread pattern has shifted, the pattern can be adjusted left
and right by loosening the two knobs on the discharge chute
and moving the chute closer or further away from the impeller.
Settings of A, B and C are provided as reference.
operation
1. Check the product package for the rate setting, and recom-
mended swath width. Loosen rate control knob and slide rate
plate to the proper setting. The pattern is controlled by loosen-
ing the two knobs on the discharge chute and moving the chute
closer or further away from the impeller (setting A, B or C). See
“Pattern Adjustment” for details.
2. Always ll the spreader on the driveway or sidewalk, NOT on
the lawn. Make sure screen is in the hopper and spreader is in
the “O” position.
3. Start spreader moving before opening port. Close before
stopping. Always push spreader, never pull.
4. Hold handle so top of spreader is level. Tipping the spreader
too far can cause uneven spreading.
5. The settings and swath widths on the product label are
recommended starting points. Always check the delivery rate
and pattern on a small area before treating a large area. Actual
delivery rate can vary due to weather conditions, operating
variables and condition of the product being applied. See “How
to determine spreader settings and spread width” for details.
6. Push spreader at a normal walking speed, roughly 2.5 mph.
Apply header strips around area to be treated. Space strips
across the area as shown. Keep material o ower beds, side-
walks, etc.
7. When transporting spreader, make sure that it is in the “o”
position.
8. Empty spreader after each use. Return leftover materials to
its original container.
PATTERN ADJUSTMENT
4
Two major factors should be considered when determining
correct spreader settings of any project:
1. The product application rate, or the amount of material
applied per 1,000 square feet.
2. The eective pattern width, or the actual width in which ma-
terial is applied. Label settings are a guide and can be aected
by numerous factors.
A simple visual pattern test can be made by operating the
spreader over a non-turf area and evaluating the pattern. A
more accurate method is to place a row of common disposable
aluminum cake pans approximately 1 foot on center. Set the
rate plate at a middle setting and make 3 or 4 passes in the
same direction as shown. Pour the material collected from each
pan into individual bottles of the same size. Set them side by
side in order and visually inspect their volume. If the pattern
is not centered (example: volume in bottle #2 left not equal
to bottle #2 right), adjust the discharge chute up or down as
described in “Pattern Adjustment” section.
Once the pattern is uniform, the eective pattern width can be
determined. The eective pattern width is the distance out from
the spreader to a point where the amount of material is 1/2 the
average amount in the center pans. This distance is multiplied
by 2 to achieve the total eective pattern width.
Knowing the eective pattern width, for example: 10 feet.
Measure a distance equal to 100 square feet ( 10’ x 10’ swath).
Determine the product coverage in pounds / 100 sq. ft. by
taking the weight of the product and dividing it by the recom-
mended square foot coverage (add two zeros to the weight of
the bag).
Example:
Product weight: 25 lb.
Coverage: 5,000 sq. ft.
2500 lbs ÷ 5000 sq. ft. = .5 lbs / 100 sq. ft.
Weigh out 15 to 20 lbs of material and spread over 100 sq. ft
area. Weigh remaining material left in hopper and adjust rate
setting as required. Repeat test until application rate is correct.

The following provides approximate A.M. Leonard AM70P and AM70S setting when only the product weight, square-foot coverage
and visual inspection of material is available.
The conversions should be used as guidelines for establishing proper rate settings for the particular product being applied. Steps
for obtaining the most accurate settings are outlined in the “How to Determine Spreader Settings and Spread Width” section of this
manual. These settings are approximate and may vary due to physical characteristics of the product. Walking speed, wear, condi-
tion of the turf and humidity may cause actual rate settings to deviate. No expressed nor implied warranty or guarantee is provid-
ed as to the coverage or uniformity indicated by these rate settings.
The AM70P / AM70S was calibrated during assembly of the
threaded control rod in step 4 of the assembly instructions
section. However, it is good practice to occasionally check the
calibration to ensure optimum performance.
1. Pull the On/O lever to the “OFF” position. Set the rate control
plate to setting “B”.
2. Flip On/O control lever to the “ON” position. Check the port
opening. It should be “just” open. If adjustment is necessary,
continue to step 3.
3. Loosen the rate control knob and slide the rate plate until the
port is just opening. Loosen pointer screw and move pointer un-
til it aligns with “B” on the rate plate. Re-tighten pointer screw.

1. Never store unused material in spreader, return product to its original container.
2. Wash spreader thoroughly after each use and dry completely in sun or heated area.
3. Grease axle bearings in frame. Oil the impeller shaft bearing in hopper, pivot points
on the shut-o plate and the spring in the housing behind the rate plate.
4. Remove gear cover and wash gears thoroughly. Oil all bearing areas and face of
gear teeth. Lubricate gear teeth with dry graphite. Re-install gear cover.
5. Gear mesh should be checked on a regular basis during high use periods. Clearance
between the axle gear and pinion gear should be minimal but not tight. if adjustment
is necessary, loosen axle collar set screw and hold gears together. Slide axle collar
against the gear support and tighten axle collar set screw. Spin drive wheel. Gears
should run freely and smoothly.
6. Impeller surface should be cleaned periodically to remove build-up of product.
Build-up can cause the spread pattern to change.
7. Tire pressure should be 20-25 PSI.
